Patented Dec. 17, 19 19 ,4 HORNE) OILING SYSTEM.

To all whom it may concern:

Be it known that I, W'ALTER ALEXANDER RARIG, a citizen of the United States, residing at Oakland, inthe county of Alameda and State of California, have invented certain new and useful Improvements in Oiling Systems, of which the following is a specification.

This invention relates to oiling systems for internal combustion engines, and more particularly to a system adapted to be attached to those engines which at the present time are oiled by What is commonly known as the splash system.

The principal object of my invention is to arrange mechanical devices whereby oil is taken from the sump, forced through a improvements in sight feed pipe and then delivered at one or more suitable points in the crank casing Where it is most effectively distributed to the various moving parts.

Another object or" my invention is to provide an improved means for attaching the pump to a moving part of the engine and in general to provide a simple and efficient system for the purpose set forth. a

With these and other objects in view my invention consists in the novel construction and combination and arrangement-of parts herein illustrated and more specifically pointed out in the appended claims.

Referring to the accompanying drawings forming a part of specification,

Figure 1 is a view in side elevation showing my improved oiling system attached to an automohile engine,

Fig, 2 is a view in plan showin the man ner in which the pump is .attac ed to the cam shaft of the engine, and also showing the inside of the attaching nut Fig. 3 is a view in front elevation of the gear pump used in connection with the oiling system.

Referring to corresponding parts of the several views by the same numerals of refer once, 1 denotes the engine casing, 2 the oil sump or reservoir, 3 the cam shaft, pivotally mounted in hearings 4.- and which 18 driven by the gear 5 from the crank shaft of the engine. Casing 6 surrounds the end of the cam shaft and When installing my improved system, I provide an opening 7 through the end of this casing and thread the end of the cam shaft, as shown at 8. The oil pump is denoted by 9, and I preferably use a gear Specification of Letters Patent. Application filed May 24, 1916. Serial No. 99,515.
